History & Heritage

Monaghan sits in the drumlin belt of south Ulster — a landscape of rounded hills, small fields, and winding lanes that shaped the particular sensibility of the county's most famous son, the poet Patrick Kavanagh. Kavanagh's poems about Monaghan — 'Shancoduff,' 'Inniskeen Road: July Evening,' 'The Great Hunger' — are among the most precise accounts of Irish rural life ever written.

The McMahons were the ruling Gaelic family of Monaghan — Lords of Oriel — until the Plantation of Ulster. Their territory, Muineachán (meaning 'thicket'), gave the county its name. The McMahons resisted Anglicisation until the beginning of the seventeenth century.

Monaghan was one of the three Ulster counties retained in the Irish Free State after partition in 1922. The border it now shares with Fermanagh and Tyrone in Northern Ireland was one of the most contested frontiers in Europe during the Troubles.

The County Monaghan Diaspora in America

Monaghan emigrants went heavily to England and, from there, to the United States. The county's textile industry — particularly in the nineteenth century — linked it to the industrial cities of Lancashire. Monaghan families in America tended to settle in the urban northeast.
